Listen, O seeker, to the divine teaching as Lord Krishna revealed it to Arjuna on the sacred battlefield. Krishna began by illuminating the workings of the three gunas, the fundamental qualities that shape all embodied existence. “Know, Arjuna,” he said, “that rajas is the quality of passion. It arises from craving and attachment, binding the soul to ceaseless activity. Tamas, on the other hand, is born of ignorance. It deludes all beings and binds them through heedlessness, laziness, and sleep. Sattva, pure and luminous, attaches one to happiness; rajas to action; tamas, veiling knowledge, leads to heedlessness.” He explained how these gunas take turns prevailing: “When rajas and tamas are subdued, sattva shines forth; when sattva and tamas are overcome, rajas dominates; and when sattva and rajas are suppressed, tamas prevails. When the body is filled with light at every gateway, know that sattva has increased. When rajas rises, there is greed, restless activity, constant undertaking of actions, and unending craving. But when tamas swells, darkness, inertia, heedlessness, and delusion take hold.” Krishna described the consequences of these qualities at the moment of death. “If one departs when sattva prevails, he attains the pure worlds of the wise. Dying in rajas, one is reborn among those attached to action. Dying in tamas, one is born among the deluded. The fruit of sattvic actions is pure; from rajas comes suffering; from tamas, ignorance. Sattva gives rise to knowledge, rajas to greed, and tamas to negligence and delusion. Those established in sattva rise upward, those in rajas remain in the middle, and those sunk in tamas descend downward.” He continued, “When the wise see that all actions are performed only by the gunas and realize what lies beyond them, they attain My state. Transcending these three gunas, which spring from the body, the soul is freed from birth, death, old age, and suffering, and attains immortality.” Arjuna, eager to understand, asked, “By what marks is one known who has transcended the three gunas, Lord? How does he behave, and how does he go beyond them?” Krishna replied, “He who neither hates the presence of light, activity, or delusion, nor longs for their absence; who, seated as a witness, is unmoved by the gunas, knowing ‘the gunas alone act’; who is equal in pleasure and pain, established in himself, treating clod, stone, and gold alike; who regards the pleasant and unpleasant equally, remains steady, and is the same in praise and blame; who is equal in honor and dishonor, treats friend and foe alike, and has abandoned all undertakings—such a one is said to have transcended the gunas. And he who serves Me with unwavering devotion, through the yoga of devotion, transcends these gunas and is fit to become Brahman. For I am the foundation of Brahman, of the immortal and imperishable, of eternal dharma, and of absolute bliss.” Then Krishna spoke of the cosmic tree. “They speak of the imperishable ashvattha tree, with roots above and branches below, whose leaves are the Vedic hymns. He who knows this tree knows the Vedas. Its branches stretch downward and upward, nourished by the gunas, with sense objects as its shoots. Its roots, spreading below, bind the world through action. Its true form is not perceived here, nor its end, nor its beginning, nor its foundation. But, armed with the strong axe of detachment, one must cut down this deeply rooted tree. Then, one must seek that path from which there is no return, taking refuge in the primordial Person from whom all ancient activity has flowed.” He described the qualities of those who reach this state: “Free from pride and delusion, having conquered attachment, ever dwelling in the Self, their desires gone, liberated from the dualities of pleasure and pain, the undeluded reach that imperishable state. Neither the sun, nor the moon, nor fire illumines that realm; having reached it, one never returns. That is My supreme abode.” Krishna revealed, “A portion of My own Self, having become a living being, draws to itself the senses and mind, which abide in nature. When the Lord assumes a body or departs from it, He takes these senses and mind along, just as the wind carries scents from their source. Presiding over the ear, eye, touch, tongue, and nose, as well as the mind, He experiences the objects of the senses. The deluded do not perceive Him as He comes, stays, or departs, but those with the eye of knowledge see Him. Striving yogis perceive Him within themselves; but those of unrefined mind, though striving, do not see Him.” He continued, “Know that the radiance residing in the sun, which illumines the whole world, and that which is in the moon and in fire, is My own brilliance. Entering the earth, I sustain all beings by My energy; becoming the nourishing moon, I foster all plants. As the digestive fire, I reside in all beings, digesting the four kinds of food with the incoming and outgoing breaths. I am seated in the heart of all; from Me arise memory, knowledge, and their removal. I alone am to be known through all the Vedas; I am the author of Vedānta and the knower of the Vedas.” Krishna spoke of the two kinds of beings: “In this world, there are the perishable and the imperishable. All creatures are perishable; the unchanging is called imperishable. But there is another, the Supreme Person, the Highest Self, who, entering the three worlds, sustains them—the imperishable Lord. Because I transcend both the perishable and the imperishable, I am proclaimed in the world and in the Vedas as the Supreme Person. Whoever, free from delusion, knows Me thus as the Supreme Person, knows all, and worships Me with his whole being, O Arjuna.” Thus did Krishna reveal the deepest mysteries of the gunas, the cosmic tree, the Self, and the Supreme Person, illuminating the path to immortality and the highest bliss.
